1. What is the Concentration Formula?

The concentration formula (C = n/V) calculates the molarity of a solution by dividing the amount of solute (in moles) by the volume of the solution (in liters). It's a fundamental concept in chemistry for quantifying solution composition.

2. How Does the Calculator Work?

The calculator uses the concentration formula:

Where:

• \( C \) — Concentration (mol/L or M)
• \( n \) — Amount of substance (moles)
• \( V \) — Volume of solution (liters)

Explanation: The formula shows that concentration increases with more solute or less solvent, and decreases with less solute or more solvent.

3. Importance of Concentration Calculation

Details: Concentration calculations are essential for preparing solutions, conducting chemical reactions, and understanding solution properties in chemistry and biology.

4. Using the Calculator

Tips: Enter amount of substance in moles and volume in liters. Both values must be positive numbers. The result is given in mol/L (molarity).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between molarity and molality?
A: Molarity (M) is moles per liter of solution, while molality (m) is moles per kilogram of solvent.

Q2: How do I convert grams to moles?
A: Divide the mass in grams by the molar mass of the substance (g/mol).

Q3: What are typical concentration units?
A: Common units include mol/L (M), mmol/L, g/L, % (w/v or v/v), and ppm.

Q4: Why is concentration important in reactions?
A: Reaction rates and equilibrium positions depend on reactant concentrations.

Q5: How does temperature affect concentration?
A: Molarity changes with temperature because volume changes, while molality remains constant.
